I need the best materiel for fixed target experiments using linear particle accelerators when accelerating electrons. By "best" I mean one that when the accelerated electron beam collides with it the ...

I purchased this line laser recently and I'm running into a bit of an issue. The laser shoots out at a 120 degree angle which is perfect. However, once the laser spreads to about 4.25 inches, I need ...

I'm making a 2D plot of my microwave S Parameter data and want to represent the error bars correctly.
Experimental Context:
I measure S21, (Vout/Vin), as a function of frequency and drive power with ...

How can I insulate conductors independently one off the other, where they pass through a magnetic field? Are there a techniques or alloys? There is a issue how to insulate copper wire where current ...

We have to calculate the photon yield of the scintillator NaI. We have measured his pulse height spectrum but we have no idea how to solve this problem. Can someone explain it?
The source that we used ...

Is there any cheap method by which to create tune-able optical band pass filter?
I am working with a chemical process which will fluoresce when excited by a specific wavelength of light. As shown in ...

Say one is interested in measuring the mean value an approximately sinusoidal voltage with an instrument that has an accuracy of 0.01 V, according to its spec sheet. 10 periods of the oscillation have ...

While searching for different methods of calculating Speed of light, I came across one of the methods that Fizeau discussed below which I cannot fully understand.
In short, in Fizeau’s apparatus, a ...

When we measure a physical quantity multiple times, we can calculate several values which should help us understand the whole measurement better: Standard deviation, variance, median, average, and so ...

I think you can detect a neutron event with a scintillator (neutron to photon), photomultiplier tube (photon to electric signal) system, but how would a fusion neutron's energy (2.45 MeV) be typically ...

I have two animal running trajectories. A regular one with repeated back and forth running between point A and B, like the one on top in the figure. The other one is very irregular, animal paused and ...

So I am trying to figure out the coherence length of my laser source. I am using a mach zehnder interferomter (image attached). I have theoretically calculated $L_c$ to be somewhere between 800-1200 ...

I'm working on a project that involves a scale parachute. It is vital for the project to get a good measurement of the speed it has when it lands. We still haven't built the parachute, but we need a ...

I am an amateur of experimental physics, and I would like to use a Stanford dual sr400 counter to make the photons coincidence counting to see quantum optical effects. Right now I am about to set up ...

Every piece of knowledge in science has a beginning lying in someone's experiment. I would like to know which experiment gave scientists the reason to believe nuclear fission/fusion existed and was ...

I am creating a data acquisition software, based on Sparrow's Kmax. There I would like to add a feature that will show the system's dead time.
I have already a text field that shows the real time and ...

I know that the most common type of particle tracks photography is in photographic plates, but i'm using a cloud chamber and I would like to know if there are alternative ways to take photographs of ...

I am searching for a microscopy technique in wet conditions. It must be possible to see through the specimen. ESEM is good but can't see through. TEM needs high vacuum which will boil away water. The ...

In the Bose-Hubbard model of cold atoms in an optical lattice, we consider only the short-range interaction or on-site interaction. Is it possible to realize long-range interaction similar to Coulomb ...

I have to come up with a method to measure the focal length of a concave lens that's not in my lab guidebook. So I decide that I will build an afocal system with a convex lens and a concave lens and ...

At a typical energy of about 100 GeV, a muon has a Lorentz factor
of about 1000, an electron about 200.000. The flight time to the
detector should be around 30 ns (assuming d= 10m from the collision
...

For a typical flourescent light available in the United States on a a standard 120V 60Hz line, is there information available on the decay time of the light? For example, if I am running the light a ...

I did an experiment on pendulum motion and in the method it says use the following equation to measure the velocity of the pendulum:
$$v=\frac{W}{t}$$
where $W$ is the width of the pendulum bob and t ...
